Description

DESCRIPTION

Device for aligning a stack of containers

[0001] The invention relates to a device for the alignment of a vertical stack of cuboid containers, according to the preamble of claim 1, particularly containers with side walls extending perpendicular to the bottom surface.

The invention further relates to a system for stacking such containers and for housing saving space.

State of the art 10

[0002] The parallelepiped containers of plastic, metal, wood or cardboard for housing and transporting articles are known.

To allow stacking such a container vertically without displacing them vertically, the containers are often provided with a profile on the external surfaces of the bottoms, a typically rectangular profile, 15 which can fit on the upper edge of another container.

Therefore, the containers cannot be moved laterally, and the side walls of the containers standing on top of each other remain fixed vertically.

With parallelepiped containers with a flat outer bottom surface without a profile and with only a grid bottom, the stacking is on the contrary more difficult, since the containers lying on one another 20 can move horizontally and are not fixed in position. some in relation to the others.

Due to their parallelepiped shape and side walls that extend perpendicularly towards the bottom, the containers cannot be placed either inside each other, as is possible approximately with containers with side walls that extend obliquely and slightly towards the bottom.

 25

[0003] In EP2484599 a container with side walls extending perpendicular to the bottom is presented, in whose corners respectively an protruding element in the form of a vertical column is integrated on the side walls and the column elements form a single part.

It also has elongated cavities to the internal parts of the corners, in which the column-shaped elements of a second container can fit. 30

The column-shaped elements are formed and placed in pairs, in which respectively two diagonal opposite elements as well as the diagonal opposite cavities are equally formed, while the two other diagonal opposite elements and cavities have a slightly different shape.

When the containers are stacked on top of each other, opposite diagonal elements fit into the cavities, so that the containers are fixed to each other with a certain distance. 35

When the containers are placed one on top of the other with internal spaces oriented towards each other, the column-shaped elements fit into cavities, so that a tightly closed package emerges.

[0004] GB2037709 discloses a flat-bottomed container with no profile and a lid, in which four upper corners of a rectangular angular pillar element are respectively rotated on the edge of the side walls 40 and fixed by means of ribs, which press on or on the side walls of the container.

The element also has a horizontal area in the form of a rectangular triangle, on which a cover can be placed.

Side walls, which extend perpendicular to the horizontal area, fit through openings in the form of a corresponding groove grab into a container stacked on top. Four. Five

On the inner side of the corners the pillar element extends to the bottom of the container and acts as such as a lid support as well as another container stacked on top.

[0005] US2001 / 0008251 discloses a separate recyclable and foldable container as well as a connecting piece, which is allowed to be disposed on an upper edge of an open container. fifty

Such a connecting piece has external side walls, which are arranged adherent on the outer side of the container edges, a horizontal area, which extends from the outer side walls into the container and internal side walls, which run down the area horizontal and are placed only on the inner walls of the container placed below.

 55

Description of the invention

[0006] It is the task of the present invention to create a device that allows parallel and open-bottomed containers to be stacked correctly and vertically and with at least a partially defonted bottom, for example shaped as a grid or cross, with an external flat area and in order to avoid lateral displacement 60 of the individual containers relative to each other.

[0007] A fixing element according to the invention for positioning parallel upwardly open containers in a vertical stack has the characteristics of claim 1, particularly first rectangular vertical side walls facing each other, second vertical side walls , 65 as well as a horizontal connection element.

The first side walls at a right angle that face each other have respectively interior surfaces and external surfaces, where the interior surfaces surround the right angle and the external surfaces form the exterior angle of the right angle.

The second vertical side walls are rotated to the outer sides of the first side walls or the outer angular tip of the right angle. 5

The flat connecting element extends horizontally from the center of the outer surfaces of the first side walls to the vertical center of the second side walls and closes the total exterior angle of the first side walls.

The connecting element extends horizontally respectively from the center of the first side walls positioned vertically to the vertical center of the second side walls. 10

Both the first and second side walls of the fixing element are placed perpendicular to the connecting element and extend from the horizontal connecting element perpendicularly upwards and perpendicularly downwards.

[0008] The fasteners according to the invention can be placed in continuous connection at the corners of a parallelepiped container, when the horizontal connection element is placed on the upper edge of the open container upwards.

In this case, the lower vertical half of the first rectangular side walls that face each other is inserted into the internal rectangular walls of the edge of the container.

The lower vertical half of the second side walls is added to the outer wall of the edge of the container. twenty

When the second side walls of the outer surfaces of the first side walls are turned or oriented to the outer angular tip of the right angle formed by them, or both, the edge of a container is surrounded at one of its corners by the fixing element

The upper vertical halves of the first and second side walls protrude from the edge of the container. 25

A second parallelepiped container with an external flat bottom surface that is at least provided with a deflection in the corner area, can be placed on the first container with the four fixing elements and can be placed in its position relative to the first container , on which it is placed.

In this case, the bottom edge of the container is hooked between the first and second side walls of the fixing element in continuous connection, as soon as the second side walls of the fixing element 30 are added to the outer sides of the edge of the container to the corners of the container and the first side walls of the fixing element are added to the inner sides of the lower edge or in recesses in the floor, for example along the edge of a grid structure of reinforcement of the bottom.

The first and second side walls of the fixing element cause that two containers placed on each other cannot move laterally relative to each other and thus form a vertically oriented correct stack 35.

The fixing elements remain fixed on the one hand due to the closure of the mold, on the other hand they are also held in position by the weight of the stacked container itself.

[0009] The fixing element allows the vertical alignment of piles of containers with a bottom that is deflounded at least 40 in the corner area, which is disclosed without a fixing device integrated in the state of the art.

[0010] The fixing element can also be removed and recycled easily and without tools due to the continuous attachment. Four. Five

[0011] The fixing element according to the invention is applicable on parallelepiped containers with edges of different shapes, as long as the first side walls are at a right angle to each other and the second side walls are turned from the sides external of the first side walls or of the visible angular tip or both. fifty

In this case the first side walls are formed according to the inner contour of an edge of the given container and the second side walls according to the outer contour of the edge of the same container.

[0012] In a first embodiment of the invention, the first side walls that are facing each other at right angles are separated, where the tip of the angle is open and between the side walls there is a free space 55. This allows freedom in manufacturing accuracy at the tip of the angle.

The fixing element can also be used for different containers with different rounded tips or corners inside the edge of the container.

[0013] In another embodiment the first two side walls are joined at the tip of the right angle. 60

[0014] The second side walls are formed according to the external contour of a particular container edge.

The invention therefore also comprises different embodiments of the conformation of the second side walls, which guarantee a continuous attachment to the outer edge of a container. 65

[0015] In one embodiment of the invention the second side walls of the fixing element form an arcuate area, where the convex side of the tip of the right angle, which is formed by the first side walls, is rotated.

This form is suitable for application with containers with the corresponding container edge formed with a recess in the corner of the edge. 5

[0016] In another embodiment, the second side walls of the fixing element are in the form of a curved area, where the concave side of the tip of the m of another embodiment is the second side walls of the fixing element, similarly the first Side walls are formed with one or several flat walls.

This fixing element can also be placed on the corners of an edge of the container, where the 10 second side walls are added along the outer sides of the container.

[0017] In the aforementioned embodiments, the connection element is formed superficially and with a minimum thickness corresponding to the thickness of the material.

 fifteen

[0018] The fixing element allows fixing the position of several stacked containers relative to each other relatively, so that a lateral displacement is impeded and a vertical stack alignment is guaranteed.

The fixing element allows a stack of containers, in which their bottoms are always placed on an open end of a container that is underneath.

On the other hand, this allows a stack of containers, in which the open sides are placed on the open sides 20 and the bottoms on the bottoms, where twice as large containers emerge with the last stack.

[0019] In another embodiment of the fixing element, the connecting element is formed between the first and second side walls as a separator and has a predetermined thickness for this purpose, where the first and second side walls in their vertical expansion on both sides protrude. of the horizontal area of the connecting element and of the separator equally equally large.

While in the first mentioned embodiments of the fixing element the connecting element only has a thickness, to guarantee a minimum resistance in the manufacture and the element, because of the chosen material.

In this other embodiment the thickness is larger, to achieve a predetermined distance between two 30 containers.

Such distancing allows two containers oriented towards each other to be stacked with their sides open, where a space is formed between the containers that is enlarged to the magnitude of the separator.

This allows the stowage of another container between both stacked containers.

With this, a third container in the inner space 35 of two such stacked containers can be stored respectively in the container transport.

The container volume can then be reduced by half.

[0020] In one embodiment of the fixing element with spacers, the connecting element not only has a predetermined thickness for the distance, to reach a distance of the stacked container, but also two or more projections on the second side walls, where the projections extend horizontally in the direction of the first side walls.

The projections are spaced respectively from the area of the connection element, where the distance between the connection element and a projection corresponds to the vertical thickness of an edge of the container.

Projections of this type allow an additional fixation of the fixing element to the edge of a container on the fixing in continuous connection with which a spring fastening is allowed to the edge of the container by means of the projections.

The spring clamp is also slightly removable again, with the protrusions being larger or smaller according to the material, thickness and shape of the edge of the container.

At least two projections are each further arranged diagonally, in that a first projection is arranged in a second lateral wall over the horizontal area that extends from the connecting element, and a second projection is disposed in a second lateral wall on one side. under the horizontal area that extends from the connecting element and on the other hand it is also arranged in a side wall, which extends at a right angle to this side wall, in which the first projection is arranged.

By means of two projections arranged in this way, the fixing element is fixed by at least one spring fastener to the edge 55 of a first container and by means of at least one spring fastener is fixed to the edge of a second container, where the two fasteners are arranged sideways. Different from the container.

This allows sufficient fixation of a stack of containers.

[0021] The invention comprises the aforementioned embodiments as well as any combination of the cited embodiments.

[0022] In a system for stacking parallelepiped containers with outer flat bottom surfaces, parallelepiped containers are fixed in a position by means of fasteners of the type described above and are vertically oriented. The fasteners allow 65 different combinations of stacked containers.

For example, two containers with their open ends can be stacked relative to each other, where their relative position is fixed by means of a fixing element with a connection element as a separator.

A third container may be arranged in the interior space, which is formed between two stacked containers.

Several such piles of each two containers with respectively a third container in their interior space can be stacked on top of each other in turn, so that a thickness fixing element is placed on the four upper corners of the two stacked containers 5 respectively smaller with a flat connection element according to the first embodiment. The bottoms of another stack of two containers with the third container in the interior space can be fixed and placed on these fasteners.

[0023] Other advantages of the invention arise from the successive description, in which the invention with the aid of the 10 embodiments shown in the schematic drawings is described in more detail.

Examples of embodiment of the invention

[0026] An example of the fixing element 1 according to the invention of a first embodiment for vertical alignment of parallelepiped containers is shown in Figures 1a and 1b. Four. Five

The first side walls 2 and the second side walls 3 are shown, which are vertically aligned and connected to each other by a fourth flat connecting member.

It extends horizontally respectively from the center of the first side walls 2 placed vertically to the vertical center of the second side walls 3 as shown in the side representation also in Figure 2.

 fifty

[0027] In the example shown of the fixing element, as particularly visible in the view from above in figure 3, the first side walls 2 are formed flat and rectangular straight one in relation to the other, according to the shape of the inner side of an edge of the container

The connecting element 4 extends through the outer angle of 270 ° of the right angle formed by the first side walls 2. 55

The first side walls are separated from each other, so that at the tip of the right angle formed by them there is a free space.

The second side walls 3 are the tip of the right angle of the first side walls turned as well as the outer sides 2a of the first side walls 2 turned, that is the outer sides of the walls 2, which form the outer angle. 60

In the example shown they are formed rounded and are formed according to a recess on the outer side of the edge of a container.

The second side walls 3 can also be curved outwardly according to an outwardly curved edge.

They can also, similar to the first side walls, be formed as two flat and rectangular walls facing each other, which rotate the outer sides of the first side walls. 65

Alternatively they can also form a single flat area, that the outer tip of the right angle of the first side walls is rotated, if a container has an edge with an oblique corner portion that extends to the side walls.

In any case, one or several second vertical side walls are rotated on the outer sides 2a of the first side walls 2 or at the tip of the right angle or in both places. 5

[0028] With the application as a fixing element with parallelepiped containers, therefore containers with for side walls extending towards the bottom, the connection element 4 can be joined in a corner part of the margin 5a of a container 6, as shown in Figure 4a-d, where the first side walls 2 of the fixing element 1 of the inner side of the edge 5a and the second side walls 3 of the fixing element 10 of the outer side fit that of the edge 5a.

For this purpose, the first and second side walls 2 and 3 are formed according to the shape of the edge 5a of the container. 5 .

Figures 4a-d show a fixing element 1 according to the invention arranged in one of the corners of the lower edge 5a of a container 5, with which the flat connecting element 4 is in contact on the edge 5a and 15 the first walls sides 3 and the second side walls 3 fit in continuous connection to the outer or inner side of the edge 5a.

The edge at the open and upper end as well as the bottom edge along the bottom 6 of the container 5 have a recess 5b on one of its outer sides.

The arched side wall 3 of the fixing element 1 is in this recess 5b. twenty

The first straight and rectangular side walls 2 are on the inner side of the margin 5a and engage in continuous connection to the edge of the bottom 6 formed in the form of a grid or cross as shown in Figure 4c.

The rounded surfaces of the second side walls 3 adhere in continuous connection to a recess at the bottom edge along the bottom 6, where the recess is configured like the recess 5b at the top edge of the open end of the container. 25

A fixing element 1 can be fixed both at the corners at the lower edge and also at the corners at the upper edge.

Figure 4d shows more widely the arrangement in continuous connection of the first side walls 2 in the inner walls of the edge of the container 5a of the bottom of the container 6.

To fix a plurality of containers 5 in their relatively horizontal position and stack them vertically oriented 30, fasteners 1 are fixed to the four corners of the upper margin of each container.

The corners on the bottom edge of each container are placed on the fasteners 1 of a container placed below and thereby fixed in position.

Therefore, many containers 5 can be stacked vertically on top of each other at will.

 35

[0029] An embodiment of the fixing element 11 according to the invention according to Figure 5a in turn has first, internal and rectangular side walls 12 that are placed facing each other and, second, external side walls 13 where the second walls laterals 13 are rotated to the external sides of the first lateral walls 12.

The first and second side walls 12 and 13 are connected to each other through a connection element 14a 40 b, where the connection element 14a, b is formed as a separator.

As such, it presents in this embodiment on the one hand a horizontal surface part 14a extending from the center of the vertical expansion of the first side walls 12 to the center of the vertical expansion of the second side walls 13.

The connecting element also has ribs 14b for the reinforcement of the fixing element 11 as well as the conformation of the separator, in which the ribs have a height equal to a desired distance.

Therefore, the connecting element 14 has a vertical thickness equal to the height of the ribs.

From the second side wall 13 a horizontal projection 16 extends over the vertical expansion of the ribs 14b of the connecting element and towards the first side wall 12.

In this case, there is a distance between the projection 16 and the ribs 14b of the connecting element, which corresponds to the thickness of an edge of a container, in which the fixing elements can be applied.

A second projection 15 extends from another part of the second lateral wall 13 towards the first lateral walls 12, where in turn there is a distance between the projection 16 and the vertical expansion of the ribs 14b of the connecting element, which corresponds to the thickness of the margin of a container.

The two projections 15 and 16 are moved diagonally relative to each other, in that on one side they are arranged on rectangular side walls stationary with respect to each other and on the other hand on different sides, that is on the upper and lower side of the element connection 14.

In another embodiment of the fixing element 11 according to two views in Figure 5c, the connecting element has no rib.

Instead, horizontal surfaces 14c and 14d extend at least partially from the second side walls 60 to the first side walls 12, respectively at a height that distances a predetermined distance from the upper and lower edge of the vertical side walls 12 , 13.

The area 14c extends a distance below the upper edge of the side walls 12 and 13, and the area 14d extends a distance through the lower edge of the side walls 12 and 13.

The protrusions 15 and 16 are similarly as in the embodiment of Fig. 5a and in turn at the edge of the second lateral wall 13, where the protrusion 16 is arranged on the area 14c or under the horizontal area 14d and extends towards the first side walls

The distance between the horizontal area 14c and projection 16 as well as between the horizontal area 14d and the projection 15 corresponds respectively to the thickness of an edge of the container, in which the fixing element can be applied.

With an application in a parallelepiped container 5, as shown in Figure 5d-g, a fixing element 11 is placed on each angle of an edge of the container 5a, where the ribs 14b of the connection element can be placed on the edge 5a, which adjust the first side walls 12 on the inner side of the edge and the second side walls 13 on the outer sides of the edge. 10

The projections 15 and 16 serve for a spring fastening to the edge 5a, in which the edge 5a is closed between the connecting element 14a.b and the projection 15.

A second container 7 is placed on the container 5, thus fixed by crushing its margin 7a between the projection 16 and the connecting element 14a, b.

The tightening effect is sufficient for this, so that a relative fixation of the containers 5 and 7 15 is achieved with respect to each other.

Depending on the strength of the material of the fixing element and the edge of the container, the projection can be formed larger or smaller, so that on the one hand a sufficient tightening effect is achieved and on the other hand the fixing element 11 can also be Solved again without edge manipulation tools.

 twenty

[0030] The fixing element 11 allows the stacking of two containers 5 and 7, as shown in figure 5e, as the two containers are stacked with respect to each other with respectively the sides open.

A distance of both containers 5 and 7 is achieved through the vertical height of the connecting element 11, so that a third container 8 can be kept in the space formed inside the two containers 5 and 7, as shown in figure 5d. 25

Empty containers can therefore be transported with a container transport in reduced volume.

On the inverted container 7 with the open side placed downwards, another container 9 can be placed, where it can be fixed in relation to the container 7 by means of a fixing element 1 of the first embodiment of the invention.

Therefore, many parallelepiped containers with flat bottoms 30 can be stacked at will by means of fixing elements 1 without distancing and / or by means of fixing elements 11 with distancing and with or without stowed containers 8.

Figure 6 shows an example of such a combined system according to the invention.

Here below are two containers 5 and 7 fixed to each other with fixing elements 11 according to Figure 5a-g, where another container 8 can be placed thanks to the spacing between the edge of both containers 5 and 7.

On the bottom-facing bottom of the container 7, a container 9 is stacked by means of fixing elements 1 according to figures 1-4.

Another container 10 is then placed on this open upward container 9 by means of the fixing element 1 according to Figures 1-4.
